The combination of early planting and abundant rains means soybean seedlings have been in cool and wet soil longer than normal this season. That combination creates the perfect breeding ground for soybean seedling diseases. In this Monday's teleconference, almost all Iowa State University Extension field crop specialists (FCS) reported occurrence of damping-off in their regions. Similar reports were received from agronomists from private companies. Replanting resulting from damping-off and other weather related soybean stand reductions has been reported by FCS varying in a range of 2 to 5 percent. Damping-off in corn is also reported.
